Redução de empeno em barra trefiladas do aço SAE 9254

In this paper we study the process of manufacture of wire drawn steel bars 9254, from rolled wire rod. These bars are used in the automotive industry for the manufacture of coil springs, which make up the system damping of several vehicles. The wire drawing process consists of the steps of pre-straightening, shot peening, drawing, cutting and polishing. The study aims to search for the configuration of process variables, which present the best result with respect to bending. To this were maintained settings prestraightening and mechanical stripping and varied angles and stringer polish being studied to replace the spinneret with a working angle, for a string with two working angles. To assist in the analysis of the results was the tool used DOE Software Minitab, which assesses the variation in results according to each parameter and the interaction parameters. It was thus possible to determine the best condition for wire drawing

Influence of standard load micro and nanopatterned in surface roughness of bleached teeth and submitted to different surface treatments?

The aim of this study was evaluate the dental enamel after whitening treatment with Opalescence Boost PF® 38%, correlating the structural alterations in the surface of the enamel with its respective pH and verify if whitened teeth submitted to different finishing and polishing techniques show similar surface texture to healthy teeth (control group). Sixty premolars were divided in 6 groups (n = 10), which had been immersed in artificial saliva during all the experiment. Protocol whitening was performed according to the manufacturer recommendations, and then the specimens were submitted to different polishing technique with Sof-Lex Pop On® disks, Flex Diamond® felt disks using two different micrometric polishing pastes (Enamelize® and Diamond Polish®) and two nanometric polishing pastes (Lummina-E Diamond and Lummina-E Alumina), according to the groups. Representative specimens were analyzed in scanning electronic microscopy (SEM). Whitening gel used in this experiment had modified the morphologic aspect of the enamel surface. It was found that two nanometric polishing pastes (G5 and G6) promoted a less rough surface compared to control group even after the whitening process.

Educação e modos de subjetivação no capitalismo contemporâneo: reflexões a partir de Zygmunt Bauman

The article aims to give a brief reflection about education in the context of consumer society from the contemporary society analyzes performed by polish sociologist Zygmunt Bauman. It’s highlighted the relationship between the educational institution and the discourse of the market and consumption that building practices that feedback into the practices and values defended by contemporary capitalism. Also it is indicated the effects produced by this relationship on the question of teaching and learning and teacher training. Finally, the article analyzes the dilemmas of the current school in the face of the weakening of human relations and their role in addressing of the problems identified.

A questão da diferença na sociedade contemporânea: reflexões a partir de zygmunt bauman

The objetive of this article is discuss the question of difference and alterity presents in analyzes of contemporary society conducted by the polish sociologist Zygmunt Bauman. The author observed that human relations are guided by a logic of cost-benefit connected with values of present in the discardability of consumer society. At the same time, it has built ways of eliminating difference through the construction of a politics of expulsion of those considered strangers. For the author, the cities are the materialization of the ambivalence of live with the other people in contemporary times, being the locus of experience approach and retraction to the other expressed by fear of the difference. The result of this process is the impoverishment relational, the feeling of loneliness and an ethical-political crisis seen that could be seen from the primacy of the private/intimate rather than the public dimention/action.

Amizade e a virtualização das relações humanas na sociedade contemporânea: reflexões a partir de Zygmunt Bauman

This article analyzes the human bonds in the context of contemporary society from the work of the polish sociologist Zygmunt Bauman. Taking as starting point the bond of friendship and relational virtualization process motivated by the development of new technologies, it was observed the occurrence in the present world an affective-relational impoverishment. As an alternative to this, it is argued the exercise of building and maintenance of dense bonds that provide an alternative to the bind model of momentary satisfaction, this time marks. Finally, it is indicated that the discussion of friendship necessarily imply on the problematization of contemporary ethics which will provide the foundation for building a new affective political.

From acoustic waves to microwaves

We present here some results of our research related to the optoelectronics and photonics and show all the experimental setups used. Starting with a discussion on the importance of the waves, we demonstrate our achievements based on employment of acoustic, optical, and microwaves and their technological use. The results concern the acousto-optic and electro-optic effects. The generalized analysis of the electro-optic effect reveals a new high induced birefringence in lithium niobate. A patented optical fiber microphone is presented, and its applications to the measurements of acoustic wave velocity in gases and in the laser ultrasound non-destructive evaluation system are discussed. Finally, the generation of microwaves by an optical method with substantial cost reduction is presented.

Differentiation and species status of the Neotropical yellow-eared bats Vampyressa pusilla and V. thyone (Phyllostomidae) with a molecular phylogeny and review of the genus

A systematic re-evaluation of Vampyressa pusilla warrants the elevation of V. p. thyone from subspecies to species rank based on its distinction from the allopatric V. p. pusilla. Morphological, mensural, chromosomal, and mitochondrial differences define each of these two taxa as divergent lineages. Vampyressa pusilla is endemic to the Atlantic Forest of southeastern South America and V. thyone is found allopatrically in northwestern South America, Central America, and southern Mexico. A molecular phylogenetic analysis of the mtDNA ND3-4 gene region using restriction endonuclease cut sites resulted in a monophyletic, although weakly supported Vampyressa ingroup with Chiroderma, and a clade of Mesophylla and Ectophylla as successive basal outgroup lineages. The phylogeny within Vampyressa, with the exception of V. melissa which is most similar to V. thyone based on karyotypes and morphology, had a topology of ((pusilla + thyone) + ((brocki + nymphaea) + bidens))).
